dc.description.abstract We study the left-right symmetric extensions of the Standard Model (LRSM) and point out that the discovery of a right-handed charged gauge boson W±R with mass in the TeV range will have profound consequences for leptogenesis. We consider the LRSM with both triplet and doublet Higgs scalars, and in both the cases we find that if the W±R with mass of around a few TeV is found, for example through a signal of two leptons and two jets that has been reported by CMS to have a 2.8σ local excess over the Standard Model background at the LHC, then it will rule out all possibilities of leptogenesis. In that case, the baryon asymmetry of the universe has to be generated after the electroweak phase transition and from the baryon number violation that can give rise to neutron-antineutron oscillation or (B−L) violating proton decay. en_US
